Negahban will debut as Ollie’s new foe, Al-Owal, in Episode 5 (which is currently titled “The Hunted”). The scimitar-wielding baddie will first set his sights on someone very close to the bow-toting vigilante.

Al-Owal’s origins are akin to Ra’s al Ghul — as in Batman’s infamous mentor-turned-adversary — in that both he and Malcolm Merlyn were (are…?) members the shadowy organization The League of Assassins.
